I've heard 700-R4s are tricky. Even more so, a computerized successor in an analog truck.
I have thought about a stoutly-rebuilt TH700-R4 to replace the TH350 in White Fang, my '67 K/10 Suburban, but that's a long way off.
I know you're about one wrench-thru-the-garage-drywall-in-frustration from re-rigging for Manual Transmission. And you're contemplating the T-5 five-speed. I'm not a fan of that unit. A friend had one and we replaced it 3 times one year. In my opinion it's too wimpy in a Truck.

For my money, I'd get a New Process A833 5-speed [or 4+OD]. They were more of a MOPAR tranny, but some mid-'80s Squarebody light duty pickups were optioned with them. The Holy Grail of transmission hunts now.
